The Hands- Pulling Reflex
The Hands Pulling Reflex is activated when you hold an infant by the forearms near the wrists and pull him towards you into a sitting position. The baby should respond by bending the arms to get up. The neck should be strong enough to bring the head of the baby up without the head lagging back. Research in the October 2012 issue of the American Journal of Occupational Therapy indicates that weak head and neck control at six months where the head lags may be another sign of increased risk for children with autism.

Arms may be constantly bent and the hands may have a tendency to remain clutched
